I have a problem with my power door locks. I checked the door fuse and looked good. I purchased this car almost 2 months ago. The power locks worked fine but the driver power door lock didn't work. My friend helped me install new door actuator yesterday but we ran across some issues after the install. The door lock buttons doesn't work anymore and neither does my Viper alarm remote to unlock/lock the car.

However, there are some weird things I came across after having a day gone by and just using/fiddling around with the car and doing research. For some reason, the door lock button inside now unlocks only but doesn't lock. So it went from not working at all to just only being able to unlock. It wasn't like this though right after the install as it didn't work at all but now it can only unlock. My Viper remote still doesn't work at all though, unlock or lock. I can also get the door lock buttons to work properly if I turn the ignition on AND have my seat belt in. It won't lock and work as it should if the driver seat belt isn't in. BTW, it's the same for both the driver and passenger door lock buttons. I can also get my Viper remote to unlock and lock my car by putting my key inside the door keyhole and slightly turning it a bit.

Would greatly appreciate suggestions and help. Thanks!

Welcome and congrats on your new-to-you Rav!

Unfortunately, this is a well-know problem with the 4.2's. If you search these forums, you will find tons of information. Also, if you use google's site-specific search (type "site:www.rav4world.com 4.2 power door lock actuator") you'll get even more links.

There's an issue with the position of the connection once you replace the actuator, because the 4.2 actuator also have a position sensor -- its apparently not like the "old fashioned" power locks. You can read it about in-depth with these threads:

and

There should be enough information is those posts to solve your problem. I'm going to be doing this repair within the next few months on my sister's 4.2, so I've been reading about it, as well. Please post back an update when you figure it out, and pictures, if possible. Good luck!

Dezahp the rod that connects to the lock actuactor has to be in a certain position for it to work properly. It is not that simple just replacing the lock actuator. Changing the rod position is the only way to make it work.
